Objective To assess the effect of vaginal pH on fetal sex determination. Background Sex determination is a very important topic. Changing of the normal vaginal pH (3.8–4.5) can affect the activity of different types of spermatozoa and therefore affect the fetal sex. Patients and methods This prospective study was carried on 20 patients coming to clinic of gynecology and obstetrics, with variable ages ranging from 21 to 37 years and free of any gynecological or obstetric disorders; vaginal swab from each case was taken on a litmus paper on preovulatory time to assess the acidity and alkalinity of vagina and define its effect on fetal sex. Results Overall, 20 patients were from different gravidity and parity. Regarding the comparison between acidic and alkaline vaginal pH and fetal sex, there were significant associations between fetal male sex and alkaline vaginal pH, and significant association between fetal female sex and acidic vaginal pH. Conclusion Vaginal pH could be used as a natural method to determine the fetal sex.
